Answer 1

Answer:

Option C is correct.

Step-by-step explanation:

Given $f(x) = e^{2x}$ is a function of x  

Now, the average rate of change of over the interval [1,b] is 20 for b > 1.

Now the expression can be written from the above condition is

$\frac{f(b) -f(1)}{b-1} =20$ .......(1)

Therefore, the above equation (1) can be used to find the value of b and option C is correct.
